Dorsey contributed a season-high six tackles (five solo) in Sunday's loss to the Saints.

Dorsey stepped in for Arik Armstead (shoulder) -- who left the game in the first quarter -- and turned in a solid performance. He has never been much of a pass rusher, but he can rack up a handful of tackles from the defensive end position. Armstead hasn't been ruled out of next week's tilt against the Cardinals, but the 49ers may want to be cautious with their young lineman as he has had shoulder problems all season. If he can't go, Dorsey would likely start Sunday.
